I like this setup. I've done something similar with POP3 on both PC and mobile: PC downloads and archives mail, but is configured not to delete it from the server for a month. Phone never deletes from the server, and at least has access to the most recent month of email, which is usually enough while mobile.
I'm intrigued by the idea of IMAP on the phone though. Are you able to sync sent mail this way? If you send mail from mobile, will the PC client get a copy of it?

Nope, I use phone mostly to browse mail, and send from there if and only if inevitable. And if the sent mail is too important to keep, I BCC myself and sort it out on the PC later. If your mail provider saves sent mail, I guess you could just fetch that; mine doesn't. Also I guess depending on your phone MUA, maybe you could fetch it from its storage. WRT IMAP, I just use it like POP3 w/ keep on, used it b/c was easier to set up. Phones are incredibly inconvenient for typing anything that's not a whatsapp blurb, so I mostly use it that way.
It seems smart to keep the mail on the server for a while, I'd be glad to know how you do that.
